could somebody help me out on the benefits of expensive phono and speaker cables?

"It might be nice to tell you friends you have 25k in meteorite sourced. 99999999999 Homium nitrided virgin Ecuadorian copper fully framulated and encased in the foreskins of penguins,  but it's still just...wire."
That is the best thing on this goofy forum I have ever read.........:-D

There is some goofy stuff, but my question was sincere.I’m not interested in a 50k system,hell I wear hearing aids.A decent cost effective tweak here and there might be worth it,and i’ll spend my money on vinyl.thanks for your post Al.

More music,more sound,more information,more imaging more definition upgrade asap.

   I would say cabling is system dependent more than anything. With 80% of the systems it doesn't matter because the system cannot resolve the difference. 
    My Living Room system which uses an above average receiver and OPPO player has old Monster and Audio Quest cables...I hear no difference in cable change outs. However my listening Room system which uses Technical Brain and heavily modified Silverline Grandeur mk II speakers is easy to hear. Schonberg makes a great bang for the bucks line of silver ribbon cables.
